srand(time(null)); printf("%d", rand()); Gives a high-range random number (0-32000ish), but I only need about 0-63 or 0-127, though I'm not sure how to go about it. Any help?

The RAND function generates a random real number between 0 and 1.
The C library function int rand(void) returns a pseudo-random number in the range of 0 to RAND_MAX.
How to Generate Random Numbers in C++ Within a Range. Similar to 1 and 10, you can generate random numbers within any range using the modulus operator. For instance, to generate numbers between 1 and 100, you can write int random = 1+ (rand() % 100).
rand() % (max_number + 1 - minimum_number) + minimum_number So, for 0-65:
rand() % (65 + 1 - 0) + 0 (obviously you can leave the 0 off, but it's there for completeness).
Note that this will bias the randomness slightly, but probably not anything to be concerned about if you're not doing something particularly sensitive.
